CHAPTER 2 – GENERAL INFORMATION
2.1 INTENDED USE
xThis tire changer has been designed and manufactured exclusively for removing and
mounting truck, bus and commercial van tires from/onto rims from 14" to 56" and a
maximum diameter of 2400mm.
xIn particular THE MANUFACTURER cannot be held responsible for any damage caused
through the use of this tire changer for purposes other than those specified in this manual, and
therefore inappropriate, incorrect and unreasonable.
2.2 GENERAL SAFETY PRECAUTIONS
xThe machine should only be used by duly authorized and trained personnel.
xIt is forbidden to use the machine for straightening rims, breaking beads of still inflated or dirty
tires, and turning, rasping, and cutting tires.
xUnder no way should the machine be modified except for those modifications made explicitly
by THE MANUFACTURER.
xNever remove the safety devices. Any work on the machine should only be carried out by
specialist personnel.
xAny tampering or modification to the equipment carried out without the manufacturer’s prior
authorization will free him from all responsibility for damage caused directly or indirectly by
the above actions.
xThe tire changer comes complete with instruction and warning transfers which are designed
to be long-lasting. If they should for any reason be damaged or destroyed, please ask
immediately for replacements from the manufacturer.
xThe machine operator should avoid wearing clothes with flapping edges. Make sure that
unauthorized personnel do not approach the machine during the work cycle.
2.3 SAFETY DEVICES
The tire changer has a number of safety devices designed to guarantee the upmost safety:
xCheck valve on the spindle opening hydraulic line (inside the swivel connector, see fig. B/1).
This prevents the wheel from falling from the spindle if the hydraulic line is accidentally
broken.
xPressure relief valve set at 130 bar ± 10% (see fig. B/2). This limits the pressure in the
hydraulic line and ensures correct operation of the plant.
xPump motor overload cut-off (inside the electric enclosure, see fig. B/3). This cuts if the
motor overheats to prevent it from burning out.

CHAPTER 4 – INSTALLATION
4.1 INSTALLATION SPACE REQUIRED
When choosing the place of installation, make sure that it complies with current
safety at work regulations.
xThe machine must be located on a flat floor of solid construction, preferably concrete. If the
floor is uneven or broken, the machine will be not stable and the platform roller cannot move
freely.
xIf the machine is installed outside it must be protected by a lean-to.
xThe following work environment conditions are applicable:
- Relative humidity from 30-95% without condensation;
- Temperature from 0-55°C.
4.2 WORKPLACE REQUIRED
xMaximum machine space requirements are 2240x1640mm with a minimum distance from
walls as shown in the diagram (see fig. B/5).
These measurements are also the tire changer working area. Persons other than
specially trained and authorized operators are extremely forbidden to enter this
area.
xPosition the tire changer lifting it with the specific bracket (1-fig. A) with the tool carriage arm
(2-fig. A) lowered all the way, the chuck (3-fig. A) closed and the sliding table (4-fig. A) at its

4.3 FOUNDATION REQUIREMENT
The tire changer should be installed on a leveled concrete floor at least 20cm thick with a minimum
concrete quality of B25 in accordance with DIN 1045 requirements (foundations).
For your reference see the drawings as well as the table below.
If a floor of this type is not available on site, fastening points of the specified concrete quality are
acceptable.
xSurface, on which the tire changer is to be installed, must be flat and well leveled in all
directions.
xInclination up to 0.25% relative to the horizontal can be compensated using suitable shims,
wedges or the alike.
When working with wheels, which weight is higher than 1000kg, it is necessary
to fasten the tire changer to the floor by means of proper anchor bolts.
xBy means of a hammer drill D.16, drill at least 130mm
into the floor passing through the holes provided on the
base frame.
xIf there is an additional floor covering (B), of if shims or
wedges are necessary for leveling (C), longer bolts must
be used.
xPlace an anchor bolt into each hole.
xMake sure the anchor bolts extend at least 125mm into
the concrete slab, as indicated in the drawings.
